  • Objective: To evaluate the corn green matter production at different sowing densities, in Valle del Mezquital, Hidalgo, Mexico.

    Design/Methodology/Approach: The DK-4018 hybrid corn was sown in the spring-summer 2021 cycle. The treatments (T) were different sowing densities: (T1) 112,500, (T2) 120,000, and (T3) 136,000 plants per hectare. The experimental design was completely randomized. The evaluated variables were: plant height at 30, 60, and 76 days after sowing (cm); final stem diameter at ground level (cm); fresh weight (g); and green matter yield (ton ha1). The results were analyzed with the SAS program (2001) and the means were compared with the Tukey test (p0.05).

    Results: The highest green matter production of the DK-4018 hybrid corn was obtained with a sowing density of 136,000 plants per hectare, with an estimated yield of 114.6 ton.Study limitations/implications: No scientific publications about the DK-4018 hybrid corn green matter production were found.

    Findings/Conclusions: With a population density of 136,000 corn plants per hectare, 114.6 ton of DK-4018 corn green matter yield is estimated.
